My 1999 Jeep Cherokee Limited was fine all day until I went to check my account balance at WG, unlocked the Jeep with my keyless remote, turned the key to crank up the Jeep and for some reason the power went on for half a second and then my Jeep went dead, there was no crank just complete silence and no power since. I need to get to work....how can I fix this? Fuses are fine battery is new and terminal.

The circuit that the fuse is on won't have power-nothing will come on or work on that circuit. You can pull the fuse out and see if the element inside has snapped apart, or the easiest way to check fuses is with a test light. On the top of all fuses, there are two small cavities or indents-one at each end of fuse top. These are test points or probes for fuses- the metal is exposed through the cavity. Ground a test light lead to a good metal bracket or bolt under the dash. Now turn key to ON-do not start engine. With key on every fuse on the car will be powered-every one. Touch your test light probe to one of the indents. If test light does not come on, it is not grounded well. Make sure you have it grounded good. Now use the probe to touch both ends of the fuse, first one end and then the other end. A good fuse will light tester on both ends of fuse-meaning the element inside has not blown. A bad or blown fuse will only light up the test light on one end of fuse. If fuse has blown, power will not pass through the fuse, but will be stopped at the fuse on the one side. Check your fuses this way and you will not have to pull the fuse out to inspect it. You can also check the fuses under the hood (all fuses, including the larger maxi-fuses).Post back if you have any questions, or unsure of my description.

the first thing to do is to remove the wires your sister conected, tape them seperately, these wires are power and ground wires and power the light in the visor mirror , they can not touch, so make sure they are apart and not touching any metal surface, tape them, one at a time.

there must be a blown fuse, did you check all the fuse boxes? there is one inside and one under the hood. start with this .

Easy way. With a test light connected to ground ( a test light is a tool that looks like a ice pick with a clear handle with a bulb inside, and a wire coming out the end with a clip on it) Connect the clip on the light to a metal ground under the dash and with the fuse panel where you can see it, touch the pointer to each side of the back of the fuses, with the key on. The light should lght on both sides of a good fuse. If a fuse lights the light on one side and not the other it's blown. For the radio to work three fuses all need to be good as theirs all the time power and key on power and lighting as the dash lights power. The cigar fuse many times provides the all the time power, But if it's blown the radio won't play. Pull one fuse at a time and look at them to see if the bar inside the fuse is good ( they can look good and be bad) back to the test light meathod, Look the fuses up in the owers manul and it'll tell you the location of the fuse but the radio fuse can be good and the radio strill not work as the cigar fuse has to be good too, There;s another fuse panel under the hood that has the main fuses near the battery, Again the test light is fastest and easiest as any fuse blown even though it's not the radio fuse can make the radio not play. Aftermarket radios can have inline fuses instlled by the radio installer and some have fuses right on the back of the radio.

If all of your lights inside and out arent working, then its sounds like an electrical isuue. that cost as much as $1500 dollars. But i would start with checking the fuses in your relay box under the hood. That is usually where the lights fuse is at. Some cars have two fuse boxes and a relay box, one fuse box is inside the car, one is under the hood, and the relay box is under the hood. So i would check the relay box under the hood or fuse box if you can find one. granted your brother checked them all, it sounds to me like an obvious blown fuse... good luck
